Biosolids as soil-amendment: evaluation of nutrient leaching in loamy-silty soil
(Corresponding) Venegas M., Fernandez G., Vidal G.
Topic:
Biowaste
Municipal sewage sludge is a by-product of wastewater treatment. The amount of sewage sludge has increased with the construction and expansion of wastewater treatment plants, while stricter policies have limited its disposal. Anaerobic digestion is a worldwide technology used in sewage sludge...Read more
Mass and energy balances of sewage sludge pyrolysis in a lab rotary kiln
(Corresponding) Mendoza L., Gómez A., Rincón S.
Topic:
Energy technologies and sustainability
The aim of this work is to study the influence of the main parameters of sewage pyrolysis in a rotary kiln on the product distriburion and energy balances. An indirectly heated rotary kiln at a laboratory scale was used (4 kg/h). An increase in the final temperature causes the reduction of the...Read more

Understory evolution related to organic fertilization in a silvopastoral system established under Pinus radiata D. Don. in an acidic soil
(Corresponding) MOSQUERA-LOSADA M., RODRÍGUEZ-RIGUEIRO F., SANTIAGO-FREIJANES J., RIGUEIRO-RODRÍGUEZ A., FERREIRO-DOMÍNGUEZ N.
Topic:
Agroforestry, forest and agricultural sustainability
Mixed pasture establishment is considered a key point to increase livestock production due to the higher quality it has compared with unmanaged shrubby species. They provide also a set of ecosystem services such as carbon sequestration and higher biodiversity. Moreover, herbaceous pasture...Read more
Removal of heavy metals from sewage sludge using combined hydrothermal pretreatment and chelate extraction
(Corresponding) Usťak S., Muňoz J.
Topic:
Wastewater treatment
The removal of heavy metals from sewage sludge using the combined influence of hydrothermal pretreatment and chelate extraction was tested. The classical method of batch extraction with chelates and the advanced hydrothermal pretreatment (HTP) extraction process with chelates were compared. Both...Read more

European and IMO framework on the disposal of ship waste - Greek legal interventions
(Corresponding) Dede P., Manologlou S., Tselentis V.
Topic:
Environmental impact of maritime transport
For almost every type of ship-generated waste, there is a variety of waste flows and on-board treatment methods. Studies show that ships use different treatment methods and often only treat part of a waste stream. This results in a difference between the amounts of waste generated and the amounts...Read more
Combining consumption-based approach and chemical analysis for identifying pharmaceuticals occurrence in hospital wastewater
Iliopoulou A., Gyparakis S., Arvaniti O., Sabathianakis I., Karagiannis E., Nika M., Thomaidis N., Kanellopoulou N., Thrassyvoulos M., Fountoulakis M., (Corresponding) Stasinakis A.
Topic:
Emerging pollutants
This study aims to compare and correlate the concentrations of pharmaceutical found in hospital wastewater via chemical analysis with those estimated based on consumption data. For this reason, wastewater samples were collected from different points of the sewerage system serving a Greek hospital...Read more
The effect of incorporating biosolids on soil quality after cotton crop management
(Corresponding) Giannakopoulos E., Makrygianni E., Evangelou E., Salachas G.
Topic:
New solutions for a better and sustainable agriculture
pilot sewage sludge (also known as “biosolids”, BS) application of 7,000 kg/ha (dry weight) was performed in the area of Lamia prefecture, central Greece, in two fields cultivated with Cotton. BS was very rich in organic matter (75%) and had high concentrations of nutrients, with all heavy metals...Read more

A review on the potential use of flammable gases from sewage systems as a source of energy
(Corresponding) Ghaffari M., Paurine A., Ali S., Mavroulidou M.
Topic:
Energy technologies and sustainability
The demand for natural resources has increased exponentially due to the consistent growth of the global population and urbanization. This has resulted to considerable environmental challenges that are potentially affecting the global sustainable development goals. Therefore, it is important to...Read more
The chemical exposome in maternal blood and placenta and the potential use of sewage sludge to prioritize hazardous substances
Gil-Solsona R., Nika M., Alygizakis N., Bustamante M., Villanueva C., Gutiérrez-Martín D., Restrepo E., Foraster M., Gómez-Roig M., Llurba-Olive E., Sunyer J., Dadvand P., Thomaidis N., (Corresponding) Gago-Ferrero P.
Topic:
Wastewater-Based Epidemiology
Chemicals are part of our daily lives and we are exposed to numerous chemicals through multiple pathways. Relevant scientific evidence contributing to the regulation of hazardous chemicals require a holistic approach to assess simultaneous exposure to multiple compounds. Currently, the main way to...Read more

Occurrence and fate of OMPs and ARGs in innovative full-scale WWTPs
(Corresponding) Rivadulla M., Suarez S., Garrido J., Omil F.
Topic:
Emerging pollutants
The presence of antibiotic resistance determinants in wastewater treatment plants (WWTPs) presents a potential risk for human health and for the environment (Manaia et al., 2018). The scientific knowledge related to this topic is still limited, while new technologies are being implemented to reduce...Read more
